Protein Name:
Phosphoglucan phosphatase DSP4, chloroplastic
|
UniprotKB/SwissProt ID: Q9FEB5 (Q9FEB5)
Gene Name:
DSP4
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Starch granule-associated phosphoglucan phosphatase involved in the control of starch accumulation. Acts as a major regulator of the initial steps of starch degradation at the granule surface. Functions during the day by dephosphorylating the night-accumulated phospho-oligosaccharides. Can release phosphate from both the C6 and the C3 positions, but dephosphorylates preferentially the C6 position (PubMed:20018599, PubMed:26231210)
